"context deadline exceeded" with consecutive requests

[NiklasBr]

  gotenberg:
      image: gotenberg/gotenberg:7.7
      ports:
          - "3000:3000"
      command: [
          gotenberg,
          --chromium-ignore-certificate-errors=true,
          --chromium-disable-web-security,
          --uno-listener-restart-threshold=0
      ]

With the following code:

$partialDocuments = [];
foreach ($document->getAllChildren() as $child) {
    $html = $document->renderDocument($params);
    $request = Gotenberg::chromium($this->baseUri)->html(
        Stream::string($child->getPdfFileName() . '--transient.html', $html)
    );
    $partialDocuments[] = Gotenberg::save($request, SYSTEM_TEMP_DIRECTORY . DIRECTORY_SEPARATOR);
    sleep(2);
}

Next step is to merge the separate PDF:s but cannot reach it because the third $child crashes Gotenberg.

Hello @NiklasBr,

Sorry for the delay. It looks like your request timed out and your best option is either to increase the time out duration with --api-timeout or give your instance more CPU/memory.

[NiklasBr]

It has the full 10 core 32GB RAM of the machine available, and it did not seem to be using a lot anyway.

I can also confirm that this happens with version 7.8.0 on a machine with more than enough resources. If I use 7.4.2 it works normally.

[NiklasBr]

I don't know what else I can contribute with in this issue. Could never resolve it on my own.

Closing this for now. Feel free to reopen this issue if it happens with the latest version.
